| RURD840, RURD860, RURD840S, RURD860S Data Sheet January 2000 File Number 4033.1 8A, 400V - 600V Ultrafast Diodes The RURD840, RURD860, RURD840S and RURD860S are ultrafast dual diodes with soft recovery characteristics (trr < 60ns). They have low forward voltage drop and are silicon nitride passivated ion-implanted epitaxial planar construction. These devices are intended for use as freewheeling/ clamping diodes and rectifiers in a variety of switching power supplies and other power switching applications. Their low stored charge and ultrafast soft recovery minimize ringing and electrical noise in many power switching circuits reducing power loss in the switching transistors. Formerly developmental type TA09616.
